SPECIFICATION forming part of Letters Patent No. 570,951, dated November10, 1896.

Application fil d July 14,1896. Serial No.599,181. (No model.) Patentedin France January 15, 1896, No. 253,182, and in England June 9,1896,110. 12,694.

' DE OOURSAO, citizens of France, residing at Vivonne, (Vienne,) France,have invented certain new and useful Improvements in Vater-Wheels, (forwhich we obtained French Letters Patent No. 253,182, dated January15,1896,and British Letters Patent No. 12, 694, dated June 9, 1896 andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

Our invention has relation to a water-elevating wheel, and in suchconnection it relates particularly to the construction and arrangementof such a wheel and of the elevating-buckets thereof.

The principal object of our invention is to provide in a water-wheel aseries of buckets, each consisting of a long horizontally-arranged tube,an open-ended elbow secured to one end of said tube, and a double-U-shaped siphon connected with the other and closed end of said tube.

Our invention, stated in general terms, consists of a water-elevatingwheel constructed and arranged in substantially the manner hereinafterdescribed and claimed.

In the accompanying drawings, forming part hereof, Figure 1 is a sideelevational View of the discharge side of the wheel. Fig. 2 is a similarview of the opposite side of the wheel. Fig. 3 is a front elevationalview of the framework of one of the paddles of the wheel, together withone of the siphonic buckets held in operative position thereon. Fig. 4is afront elevational view of one of the paddles or wings, the face ofwhich is formed of overlapping boards. Fig. 5 is an end elevation ofFig. 4. Fig. Gis a front elevational view of a paddle or wing having aface of corrugated metal. Fig. 7 is a front elevation of the axis of thewheel. Fig. 8 is an end elevation of Fig. 7. Fig. dis a frontelevational View, enlarged, of one of the siphonic buckets; and Fig. 10is a front elevational View of a mandrel or rod adapted to be in sertedin the horizontal portion of the bucket to decrease its capacity.

Referring to thedrawings, A represents the axis of the wheel, adapted tobe suitably supported in bearings. (Not shown.) At either end of theaxis is located a disk a, having a series of radiating grooves orchannels a, into which the ends of the frames B of the paddles may beinserted and to which the same may be secured in any suitable manner.The frames B of the paddles or wings are held in suitable and rigidposition by means of the cross-bars b and the hoops or straps Z2.

To the framing of the paddle is secured a step-like face, either ofoverlapping boards 0, as illustrated in Figs. t and 5, or of corrugatedmetal D, as shown at Fig. 6, to constitute an irregular face for thepaddle and thereby lessen the slip of the paddle in the water. To theframe B of each paddle is secured a siphonic bucket E, substantially asshown in Figs. 3 and 9. This bucket E consists of ahorizontally-arranged tube, one end of which is open and merges into anelbow E, having a discharge-opening at its end. other end of the tube isclosed, but is in open communication with a double-U-shaped siphon-tubeF, bent, as at f and f, Fig. 9, and terminating in a straight open-endedtube f G is a rod or mandrel adapted to be inserted in the horizontalportion of the bucket E to lessen its capacity.

In Fig. 2 the arrow 1 represents the directionin which the current isflowing, the arrow 2 represents the direction in which the wheel isrotated by the current, and the arrow 3 in Figs. 2 and 9 represents theflow of air through the bucket as the bucket is gradually submerged inthe current.

The line saw of Fig. 9 represents the extreme height to which the waterrises in the siphonic bucket after the bucket leaves the water, and theline y y the height to which the water may rise in the straight portionf of the siphon.

In Fig. 2, .2 represents the position of the bucket upon its entranceinto the water, 2 the position as it emerges from the water, and a thepoint of discharge from the bucket.
